Digitized Sky Survey Image of White Dwarf Stars in Hyades Cluster

The Hyades is the nearest open star cluster to our solar system, at 150 light-years from Earth. This image is a color composite of red- and blue-filter observations from the ground-based Digitized Sky Survey. The Hubble Space Telescope's Cosmic Origins Spectrograph was used to study the spectrum of two white dwarfs that are cluster members.
